" Application filed September This inventibn relates more specificallytoa concrete mold tormconstruction n which the inner faces oithe outsidewalls of-a-con structure for the attachmentof floor slabs, and verticalpartitionwalls, the recess mold crete building structure are provided atintervals with recessesfhaving metal. attaching rods extendingthereintonfrom the wall :torms andthe metal attaching rodsbeing soclisposed relativeto the outside wall structure that the same w llpresent no interference' to the movement of the outside wall slipv formsduring the pouring of the walls.

- In the pouring ofthe outside walls of a; concrete'building provisionmust be made for;v attaching the floor slabs and vertical ,wall 1partitions to the inner faces of the Outside walls as the same arepoured. VVlieneta-- vtionary mold forms vare employed no difiicult-y isexperienced in forming such recesses,

but where inovableforms oftheslip type 1 are employed considerabledifficulty has been experienced p especially asthe floor and partitionattach in forming such recesses,

By means of project laterally from the the recess mold formsherein aftermore particularly describedthe recesses may be readilyfliormed at thedesired inter; vals in the building walls andlthe' attaching v rods areso disposed as toofier no inter ference to'the movable wall mold forms.we
